The Integrated Use of Organic and Inorganic Fertilizers on Production and Soil Fertility in Ethiopia

Soil fertility decline is a big issue in the Agriculture of Ethiopia. The depletion of soil fertility is the main problem to sustain agricultural production and productivity in many countries. Soils in Ethiopian have low levels of plant nutrients due to their removal by erosion and leaching by high rainfall. One of the major constraints for crop production in Ethiopia is improper nutrient management. Organic fertilizer improves physical and biological activities of soil but they have comparatively low in nutrient content, so larger quantity is required for plant growth. However, inorganic fertilizer is usually immediately and fast containing all necessary nutrients that are directly accessible for plants, but the continuous use of inorganic fertilizers alone causes soil organic matter: degradation, soil acidity, and environmental pollution.

So the integrated nutrient management system is an alternative system for the sustainable and cost-effective management of soil fertility by combined apply of inorganic with organic materials resulting in rising soil fertility and productivity without affecting the environment. In this review the improvement of soil fertility and crops production (Girma Chala and Gebreyes Gurmu, 2018) Conducted an experiment on Organic and Inorganic Fertilizer Application and its Effect on Yield of Wheat and Soil Chemical Properties of Nitisols the research finding output at Holetta Agricultural Research Center in 2014 to 2015 these results of soil analysis after harvesting revealed that application of organic fertilizer improved soil pH, OC, total N and available P, the highest wheat grain and biomass yield (6698 kg/ha and 19417 kg/ha respectively) were obtained from the application of 50% VC and 50% N and P followed by full dose of recommended rate N and P from inorganic fertilizer resulting in 6241 kg/ha grain and 18917 kg/ha biomass yields respectively.

The objective of this review has assessed the effects of integrated organic and inorganic fertilizers on soil fertility and productivity. The study revealed that the appropriate application of organic with inorganic fertilizers increases productivity without negative effect on yield quality and improves soil fertility than the values obtained by organic or inorganic fertilizers separately.

  Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

  This review paper investigates the impact of integrated organic and inorganic fertilizer use on soil fertility and crop production in Ethiopia. It aims to assess the advantages and disadvantages of using both organic and inorganic fertilizers separately, and then explores the benefits of combining them for improved soil health and agricultural yield. The study focuses on the effects of this integrated nutrient management system on various crops, including maize, rice, wheat, tomato, and teff.

  • Soil fertility decline as a major issue in Ethiopian agriculture
  • The advantages and disadvantages of using organic and inorganic fertilizers separately
  • The benefits of integrated nutrient management for sustainable soil fertility
  • The impact of integrated fertilization on the yield of various crops in Ethiopia
  • The environmental implications of different fertilizer management practices

  Zusammenfassung der Kapitel (Chapter Summaries)

  The first chapter of the review introduces the problem of soil fertility decline in Ethiopia, highlighting the need for effective nutrient management practices. Chapter 2 delves into the details of organic and inorganic fertilizers, analyzing their individual strengths and weaknesses. The chapter examines the advantages and disadvantages of each type of fertilizer, providing a comprehensive understanding of their impact on soil health and crop growth.

  Chapter 2 also explores the concept of integrated organic and inorganic nutrient management, discussing its potential to enhance soil fertility and improve crop productivity. This section explores the positive effects of combining organic and inorganic fertilizers, emphasizing the synergistic relationship between these two approaches. The chapter then presents experimental results from various research studies that demonstrate the impact of integrated fertilization on crop yields and soil fertility.
